HealinGifts Navajo Tea, Cota Yanabah Indian Tea Greenthread Thelesperma Yanabah cut 1 ounce  CAFFEINE-FREE. Our Cota or Navajo tea had been hand-picked, cleaned, dried, and cut into small pieces from New Mexico, USA. It is often drunk as a refreshing tea, to fit your brewing method. An easier method is to use an infuser and add one teaspoon of the herb to 6-8 ounces of hot water, steep for 10 minutes, and drink, relax and enjoy a healthy herbal drink. One ounce will typically give you 6 heaping teaspoonfuls of the herb, but many reuse the serving 2-3 times.
